Abstract

The improvement of whole farm and infield irrigation efficiencies can be achieved by evaluating irrigation performance at the whole farm scale using total volumetric inputs and total production outputs. The measurement of the inputs and outputs for each sub-component of the system enables the partitioning of losses and the identification of the importance of specific loss mechanisms. The volumetric inefficiencies are usually derived from losses associated with either evaporation, deep drainage or surface run-off. The system design and the management practices adopted are also important determinants of the total losses. An accurate water level sensor is developed by NCEA for evaluating seepage and evaporation losses. This sensor is based on the pressure sensing unit with an automatic tilting rain gauge.
